libthreads: Remove

libthreads is most probably completely broken, and not the long-term
road anyway.

* config.make.in (VERSIONING): Remove.
* configure.ac: Test for pfinet assembly compatibility instead of
libthreads assembly compatibility. Do not set VERSIONING.
* libthreads: Remove directory.
* Makefile (lib-subdirs): Remove libthreads.
* doc/hurd.texi (Threads Library): Rename references to libthreads into
libpthread.
* release/rfloppy.copy: Do not objcopy lib/libthreads.so.
* release/tool-Makefile (rfloppy-solib): Remove libthreads.

- * HISTORY
- * 26-Feb-94  Johannes Helander (jvh) at Helsinki University of Technology
- *	Added mach_put_reply_port. mig_dealloc_reply_port now takes the
- *	port as an argument.
- *
- * $Log:	mig_support.c,v $
- * Revision 2.8  93/01/24  13:27:14  danner
- * 	Corrrected include of mach/mach.h to mach.h
- * 	[93/01/16            mrt]
- *
- * Revision 2.7  93/01/14  18:05:37  danner
- * 	Converted file to ANSI C.
- * 	Made argument to mig_init a void * for compatibility with
- * 	mig_init in libmach.
- * 	[92/12/18            pds]
- *
- * Revision 2.6  91/05/14  17:57:41  mrt
- * 	Correcting copyright
- *
- * Revision 2.5  91/02/14  14:20:30  mrt
- * 	Added new Mach copyright
- * 	[91/02/13  12:41:26  mrt]
- *
- * Revision 2.4  90/08/07  14:31:41  rpd
- * 	Removed RCS keyword nonsense.
- *
- * Revision 2.3  90/08/07  14:27:48  rpd
- * 	When we recycle the global reply port by giving it to the first
- * 	cthread, clear the global reply port.  This will take care of
- * 	someone accidentally calling this twice.
- * 	[90/08/07            rwd]
- *
- * Revision 2.2  90/06/02  15:14:04  rpd
- * 	Converted to new IPC.
- * 	[90/03/20  20:56:50  rpd]
- *
- * Revision 2.1  89/08/03  17:09:50  rwd
- * Created.
- *
- * 18-Jan-89  David Golub (dbg) at Carnegie-Mellon University
- *	Replaced task_data() by thread_reply().
- *
- *
- * 27-Aug-87  Eric Cooper (ecc) at Carnegie Mellon University
- *	Changed mig_support.c to avoid deadlock that can occur
- *	if tracing is turned on	during calls to mig_get_reply_port().
- *
- * 10-Aug-87  Eric Cooper (ecc) at Carnegie Mellon University
- *	Changed mig_support.c to use MACH_CALL.
- *	Changed "is_init" to "multithreaded" and reversed its sense.
- *
- * 30-Jul-87  Mary Thompson (mrt) at Carnegie Mellon University
- *	Created.
